Bug with the router class

[evokerking1]

This is my code
``// import the route
import { playground } from "@colyseus/playground"
// ...
const monitor = require("@colyseus/monitor").monitor
const express = require("express")
const app = express
const route = app.Router

// ...
route.use("/monitor", monitor)

// bind it as an express middleware
route.use("/playground", playground)

app.listen(3000)

which throws this error

$ bun run index.js
478 | end: false
479 | }, fn);
480 |
481 | layer.route = undefined;
482 |
483 | this.stack.push(layer);
^
TypeError: undefined is not an object (evaluating 'this.stack.push')
at use (/workspace/colyseus-testing-ground/node_modules/express/lib/router/index.js:483:10)
at /workspace/colyseus-testing-ground/index.js:10:7

Bun v1.1.30 (Linux x64)
error: script "test" exited with code 1
and the code that throws this error in the /lib/router/index.js line 483 or this.layer.push()

Whats require-triage label?

@evokerking1 The Triage Process indicates that it means further triaging is needed to properly classify the issue.

You wrote const route = app.Router. Is this what's actually in your code? I'd recommend reviewing the docs, which make it clear that you must call Router. That is:

const router = app.Router()

That is all my code.

Hey @evokerking1 👋

Like @nwalters512 pointed out, could you please confirm if the issue persists even after changing,

const route = app.Router

to,

const router = app.Router()
